Abstract (en)
A semiconductor integrated circuit (IC) comprising a signal path combiner, comprising a plurality of input paths and an output path. The IC comprises a delay circuit having an input electrically connected to the output path, the delay circuit delaying an input signal by a variable delay time to output a delayed signal path. The IC may comprise a first storage circuit electrically connected to the output path and a second storage circuit electrically connected to the delayed signal path. The IC comprises a comparison circuit that compares outputs of the signal path combiner and the delayed signal, wherein the comparison circuit comprises a comparison output provided in a comparison data signal to at least one mitigation circuit.
